The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.

    the heat shield became loose and was very noisy. Ended up removing the shield. It isn't really necessary just more garbage that they put on so you can go get an expensive repair from the dealer.
